I need help installing Ubuntu on my Dell Inspiron 7577.

Note, this laptop comes with windows 10 pre-installed on a SSD.

I tried installing Ubuntu 17.10 using a USB device. But as I went on with the installation it said that it didn't recognize any operating systems on my computer. It also said that I was force booting into UEFI mode and it would cause problems with the dual-boot also.

I researched and found that if I switched from RAID to AHCI the Ubuntu installation would finally recognize windows and give me the option to install alongside it.

Now the problem is, if I switch to AHCI then I cannot boot into Windows anymore.

How do I solve this? please.

I ran this: export LC_MESSAGES=POSIX; sudo lsblk -f; sudo lshw -C storage

  • You need to install AHCI drivers in Windows before switching. –  Jan 18 '18 at 09:31
  • Could you please put the storage controller in RAID mode, boot a live system (select "Try Ubuntu" in the boot menu of the Ubuntu installation medium), open a terminal (Ctrl+Alt+T), run `export LC_MESSAGES=POSIX; sudo lsblk -f; sudo lshw -C storage` and [edit] your question to include the output of the previous command sequence? Thanks. – David Foerster Jan 18 '18 at 13:10
  • @DavidFoerster Ok I added the sequence – jdstrong95 Jan 18 '18 at 16:43
  • Ubuntu recognises the storage device. Especially in fake RAID setups like yours the necessary subsystem may only be activated at a boot stage that the Ubuntu installer doesn't reach if you select it directly from the boot menu. Could you please try to start the Ubuntu installer from the live system? There's a good chance that it will recognise the storage drive and Windows installation this way. In general fake RAID setups are highly discouraged since they provide little practical advantages but involve a lot of hassle without proper driver support which the vendors rarely give to Linux. – David Foerster Jan 19 '18 at 03:05
